Temperature control method for electric oven and electric oven

Abstract

The invention discloses a temperature control method for an electric oven and an electric oven. The method comprises the steps of obtaining an environment temperature Tenvironment; determining a temperature compensation coefficient Tcompensation according to the environment temperature Tenvironment; during the operation of an electric oven, regularly detecting a core temperature Tcore of the electric oven, and compensating the core temperature Tcore with the temperature compensation coefficient Tcompensation; and determining the heating power of a heating tube according to the set temperatureTsetting and compensated core temperature Tcore compensation, and then adjusting the heating power of the heating tube in the electric oven. According to the invention, the core temperature of the electric oven is temperature compensated according to the environment temperature, the compensated core temperature is used to replace the actual core temperature for combination with the set temperatureto determine the heating power of the heating tube, in this way, the loss of heat caused by the problem of heat dissipation of the electric oven can be compensated, the influence of the environment temperature on the temperature control of the electric oven is then reduced to make the temperature control of the electric oven more accurate, and the baked food can be more delicious.

Description

Technical field [0001] The invention belongs to the technical field of kitchen appliances, and relates to an electric oven, in particular, to a method for accurately controlling the heating temperature of the electric oven and an electric oven designed based on the temperature control method. Background technique [0002] With the popularity of small household appliances in Chinese family kitchens, electric ovens, as a representative of Western typical kitchen appliances, have begun to be loved by more and more Chinese families. The electric oven can be used to make meaty barbecued foods such as roast chicken and roast duck, as well as to bake bread, pastries and other pasta. [0003] Current electric ovens determine the set temperature according to the set temperature input (or selected) by the user or the baking mode selected by the user, and then determine the set temperature according to the set temperature and the detected core temperature of the electric oven The heating pow...

Problems solved by technology

Because the current electric oven ignores the influence of the ambient temperature on the temperature control of the electric oven, when the core temperature of the electric oven is close to the set temperature, the core temperature will be about 10°C above and below the set temperature due to the difference in the ambient temperature. floating change

For example, in summer when the temperature is generally high, when the set temperature is 100°C, the core temperature of the electric oven is finally stable at about 95°C; while in winter when the temperature is generally low, when the set temperature is 100°C, The furnace core temperature of the electric oven is finally stable at about 115°C. At this time, if the electric oven is working in the fermentation mode, there will be problems such as the dough is toasted and cannot be fermented.

The inaccurate temperature control of the electric oven caused by the change of the ambient temperature will cause problems such as "cooking" or over-baking the food baked by the electric oven, which will have a certain degree of impact on the user experience.
